Do you seal your own roof penetrations?
If so, how is it best done?

Thanks.

After many years of out of pocket money, and almost losing our insurance, we let the roofing contractor do the penetrations and close, no more legal claims.
Our insurance company told us if we did roof penetrations they would not accept us as insured. Most claims are paid and closed, however, with roof penetrations the claim can go on for years. What you may think you are saving by doing it yourself, may cost you your business.
The retail store, where we are working this week, has a claim with the AC contractor for $60,000 damage, due to a penetration leak.
The owner paid the additional $400 to have the roofer do the job, but the AC guys figured they would save money by doing it.

I'm used to the owner insisting that the roofer do it to keep the warranty. - for commercial work.

What kind of roof are you talking about?
residential, asphalt, cedar shake, slate, metal?
commercial asphalt, rubber, membrane, metal?

Jps,
As you said, the commercial customers will not risk the loss, the residential customers can and do hit you for claims even years after the installation. The Fans only installer in my area had over 150,000 in claims from residential vent installs he did, he went broke and is out of business.
We tell the customer to have the roofer install the housing, and we will wire it.

Some of the towns around me have absolutely required a licensed roofing contractor to seal penetrations when they show up on prints. I will use a roofer when the penetrations are at deck level, but not for pre-existing EZ curbs(the rubber ones w/concentric sleeve-things). It's hard enough on liability for electrical without worrying about water damage. I don't mind giving that hassle away, how many times does water show up exactly where the leak is? How long can it take to confirm to be sure that YOUR penetration is the one leaking?
